Press releases

SMART.WI. Witzenmann brings a digital expansion joint to market

22 Aug 2022

With its SMART.WI, Witzenmann is blazing a completely new trail on the flexible pipeline elements market. This technology line plugs the safety and monitoring gap that has previously existed in the industry's pipeline networks.

The SMART.WI technology allows pipeline components to capture and analyse a pipeline network's essential system data (pressure, temperature and movement cycles) using a sensor system. This is transferred into a Data Cloud through a secure interface and prepared and made available to the customer on an individual basis. With this, Witzenmann becomes the first company in the industry to offer its customers a solution that allows passive pipeline elements such as expansion joints to be monitored in a vendor-neutral way.
